List two examples of how chemical or nuclear energy can be transformed

Chemical energy can be transformed into electrical energy and mechanical energy.

Explanation:

Chemical Energy transformed into Electric Energy - widely exploited by batteries. The chemical reactions that are taking place in these devices can be used as a direct source of electrical energy. Some may be reversed and some non - reversible are called rechargeable. Never attempt to recharge regular batteries as there may be an explosion with burns and material and personal damage. Chemical energy transformed into mechanical energy: An explosion is always accompanied by a shock wave. The shockwave is nothing but the air being moved very quickly, a kind of supersonic wind that is accompanied by a crash. Explosives are an example of this type of transformation.
